Trent Painter is in his seventh season as an assistant coach for the University of California San Diego women's soccer program in 2017. His primary responsibility is to direct the Triton goalkeepers. He also served in the same capacity for the UCSD men's team for four years from 2011-14.

Along with legendary head coach Brian McManus and associate head coach Kristin Jones, Painter was a member of the 2016 National Soccer Coaches Association of America (NSCAA) Division II West Region Staff of the Year under the award's new format.

Painter has developed his goalies to achieve great success during his time in La Jolla. Kelcie Brodsky earned postseason recognition from the California Collegiate Athletic Association (CCAA) for each of her four years in the program from 2012-15, with a pair of second-team All-CCAA selections. She broke an 11-year-old school record for single-season saves (114) as a freshman in 2012, adding NSCAA All-West Region Second Team distinction with the sixth-best save percentage (.884) and 15th-best goals-against average (0.595) nationally. Brodsky later took over UCSD's career saves mark.

Itzel Gonzalez took over for Brodsky in 2016, and all she did was post 15 individual clean sheets, a single-season record for the program's NCAA Division II era, and earned All-America, All-West Region and All-CCAA First Team distinction. UCSD managed to do something that the storied program had never done before, producing an unbeaten and untied CCAA mark of 12-0 en route to a first CCAA regular-season crown and then a record 10th and second consecutive CCAA Tournament banner. The Tritons fell to eventual national champion Western Washington in the West Region final, 2-1 in overtime in Golden, Colo., to wind up with a 19-3 overall record.

In his first go-around on the La Jolla campus, Painter mentored Kristin Armstrong, a third-team Daktronics All-American as well as the Daktronics West Region Player of the Year and the CCAA Most Valuable Defensive Player in 2011. She was second in the nation in GAA (0.348) and fifth in save percentage (.892).

On the men's side, Painter coached two-time All-American and two-time CCAA Most Valuable Defensive Player Josh Cohen from 2011-13. Cohen led all of Division II in GAA (0.397) and save percentage (.898) as a junior in 2012, and was fifth in GAA (0.517) a year later while again pacing the league. Cameron McElfresh took over and picked up All-CCAA honorable mention in his first season as the full-time starter in 2014, finishing ninth nationally with a 0.652 GAA.

In total, Painter's pupils have been named an All-American four times and the CCAA Most Valuable Defensive Player on three occasions, and garnered All-CCAA recognition nine times. Cohen has gone on to start for Burlingame Dragons FC in the Premier Development League (PDL), Orange County Blues FC of the United Soccer League (USL), and currently Phoenix Rising FC in the USL.

In addition to his duties at UCSD, Painter has been closely involved with San Diego youth soccer over the last several years. He currently works in the La Jolla Impact club system, and is the girl's varsity head coach at San Diego Jewish Academy (SDJA).

Painter previously trained goalkeepers for the Del Mar Carmel Valley Sharks, doubling as the head coach for San Pasqual High School's junior varsity team. He came to UCSD from nearby Cal State San Marcos, where he instructed the goalies in 2010 while also coaching a pair of U-11 and U-12 boy's teams for Villa FC.

Painter guided the Fury FC boy's U-16 squad to Rotary Cup and Presidio League titles in 2008. His sides then finished first in the Charity Cup and third at the Nott's Forest Cup in 2009.

Painter earned his bachelor's degree in liberal studies from Cal State San Marcos in 2011.
